This document contains information on the replication files and software information for Holbein, John B. and D. Sunshine Hillygus. �Making Young Voters: The Impact of Preregistration on Youth Turnout.� American Journal of Political Science. 60(2): 364-382.

Software information: The analysis was run using Stata version 11.2.  The replication files include 2 coding files:
1. Replication Code 10.22.2014.do: Stata code to replicate analysis reported in the paper.

2. HolbeinHillygus_erratum_8202016.do: Stata code to replicate the analysis reported in the paper erratum, a correction to Table 2, model 1.

The replication files include 7 data files.  

For the analysis using the Current Population Survey, two data files are provided:

1. CPS data 2.5.14.dta: The primary data file for the analyses using the CPS.  

2. CPS state controls 3.24.14.dta: The state level controls used in the CPS application.  Can be merged by the state-year variable to the overall CPS data.

For the analysis using Florida data, 5 files are provided:
1. Pre-Reg FL Data 8.6.13.dta: The primary data file for the analyses using the Florida data.  

*Note on the birthdays in this file.  These are coded as numerical, so we can use them as our running variable.  They span from 5/4/1990 to 5/4/1991, with lower numbers being earlier dates.  When you combine this with those born in other years, the birthdates should correspond with�9620=May 2, 1986 and 12542=May 4, 1994.

2. Pre-Reg FL Data 8.6.13 condensed.dta: Contains some additional controls.

3. 87-90 fl registers 2.dta & 91-94 extension condensed.dta: Contains information on those who registered before and after our 6 month window in 2008. Used to include data from 2004 and for our last figure in the online appendix.

4. 2004 and 2008.dta: Corresponding data from the 6 month window on either side of the 2004 election, along with a stripped down version of our 6 month window around the 2008 election cutoff.

5. school performance.dta: Contains some additional controls that we use for our mechanism exploration.
